In Part 1 and Part 2 of this research series, we discussed some of the drivers in how procurement services are increasingly consumed in the market. In this next installment, we will evaluate the market itself and the spectrum of service types/sectors within it. Defining a market is not a one-dimensional activity. Markets are segmented along multiple variables, which we discussed in the previously mentioned research, but there are a few key dimensions worth exploring. We will not look at the traditional dimensions such as spend magnitude, market complexity, business impact, level of market fragmentation, etc. We assume that the practitioner has a fairly good understanding of major segments of management like consulting, outsourcing, contingent labor, etc.
